560se egine and trans help needed :) - PeachParts Mercedes-Benz Forum

Phillblanchard · #1 12-05-2006, 09:52 AM

Firstly hello to everyone, ive been reading through this site for a few days now and hope that i may be able to get some help as im in a little bit of a sticky patch

i recently bought and engine and transmission from a 560se allegedly a 1991 model. cant verify the year.
Am intending on using it in a wee project (id rather not say what as i dont want to be flamed by board members for butchering such a fine MB, it wasnt me!)
Basically the chap i bought it from has gas axed through everything to get it out of the vehicle as fast as possible. ive got wires and vac pipes all over the place.

Is or are there some form of service manual for the engine that will tell me what does what and where, so i can strip off all the parts i dont want/need?
The way its looking it looks easier to strip and Megasquirt it, but i can see various wires and vac pipes going to the g/box, what would these be for and could it function without them?
Theres no box of tricks attached to the dizzy, just a bunch of chopped wires *holds head in grief*

The engine code is 117 968 and thats about all i can definitely tell you people

basically any help, pics, info, links or a friendly 'what were you thinking of' would be greatly appreciated. Many thanks in advance, Phill.

any flames will be friendly.

"Gas ax" must be a British term, but I like it. I'm not sure if you're talking about an acetylene torch or a chain saw, as if it mattered.

I don't think there were electronic transmissions in the '91's, but I could be wrong. Can you find a number on that part? If it's not electronic, there will still be wires for the starter lock-out and reverse light, a vacuum line for the modulator and of course the fluid lines that run to the cooler (in the radiator).

As far as the engine is concerned, the Megasquirt may be the way to go. Otherwise you could get a Holley or other aftermarket fuel-injection system. If you know what car this came from, you might be able to get the service information on CD or DVD from the factory for as little as $20 plus shipping.

gas-axe means acetylene cutting torch.

Whats the "dizzy" and what are vac pipes?

Vacuum lines? I cannot imagine why someone would chop them however.

Phillblanchard · #6 12-07-2006, 07:54 PM

thanks for the replies!

ok in the order received, im intending on putting the engine and trans into a trike. along this guys lines but with more beef.
http://www.chrisireland.co.uk/trikes/Meglomaniac/trike.html

Gas axe is acetylene cutting. in this case with a good dose of madness

but the chainsaw idea made me smile

ill get the number from the 'box tomorrow and post it. The car was a 560se allegedly a '91 cant confirm.
were there many differences give or take 3-4 years? as far as i can tell 560se's were not made after 91? im not sure.

Dizzy is distributor, vac lines are vacuum pipes. ive no idea why these have been axed but they are definitly melted and of no use.

ive got a pic or three of the engine and can take more if anyone wants to see to confirm any thoughts on what to do?

i wouldnt mind retaining the KE jet setup but if its going to cost more than the megasquirt does to fix it then ill just strip it off.

Thanks..... yes, please post the photographs of the areas in question- they may be of the utmost help. The hoses are melted inside the glovebox compartment? Yes- the photos may help.

ASAIK, 560's last year was 1991- at least in the USA - then the "all new" S-class debuted in 1992.

I personally have never heard of a 560SE. I guess it was only available in Europe and is just a shorter wheelbase model? The only 560s I have saw were extended wheelbase models- entitled- 560SEL. Other than the coupes. I think there was also a convetible? 560SL?

Phillblanchard · #8 12-08-2006, 10:23 AM

Hi again,
yes as far as i can tell the 560se was a short wheelbase version, not many were made which made cutting this one up a crime!
its hammering it down at the moment so ill have to wait till it dries up some before i can unwrap it and take the pics.

Phillblanchard · #9 12-09-2006, 01:46 PM

right ive got everything sorted for taking the pics and the engine is now in my garage.
ill get some pics sorted soon, but theres a couple of bits which are easy to describe, if anyone may be able to identify them,

theres a round pump type thing with two pipes coming form it, below the distributor, whats this?

from the front of the engine, lh side bottom, there is a big canister type object with 2 pipes coming from it. looks like an old fashioned oil filter housing, is that what it is?

there is a white vacuum pipe and a red vacuum pipe coming out of the gearbox dangling around. would these need to be connected to something and for what purpose?

looking at the front of the engine, on the lh side top, there is an object with what looks like a motor unit with a bunch of wires coming from it, maybe about 6 wires. maybe a cruise control unit?

sorry about the descriptions, it just to keep my curiosity at bay till the morning heh

Phillblanchard · #10 12-12-2006, 09:19 AM

heres the pics.
ive labelled the bits which i need to know about.
if anyone can help, please fire away!

incidently are these engines dry sump types? if so is that the oil pump below the distributor? where should the pipes go to and from? have a look and let me know!

thanks for any help in advance!
Phill.

david s poole · #11 12-12-2006, 09:52 AM

okay.a-1=pwr steering pump reservoir. a-2=rear suspension self leveling pump.a-3&4=vac line and kick down cable.a-5=vac line to modulator.a-6=cruise control actuator.a-7=oil filter housing.a-9=vacuum line for pwr brake booster.a-10=heater hose.a-11=vac line for instrument panel.a-12=heater hose. no these are not dry sump motors.

wbrian63 · #12 12-12-2006, 09:54 AM

OK - here goes:
A1 - Power steering pump
A2 - unknown - possibly oil pump
A3 - Transmission Bowden cable - should attach to the throttle linkage - controls transmission upshift points.
A4 - Vacuum signal for transmission upshift delay. This causes the tranny to hold the first shift a bit when the weather is cold and the car is first started up - supposed to help heat the catalysts faster. Far as I know, this can be capped at the transmission without issue.
A5 - Manifold vacuum to transmission modulator
A6 - some sort of pump - others will know what this is.
A7 - Oil filter
A8 - engine wiring harness
A9 - unknown - where does this pipe connect to on the engine - block or intake? It looks like there used to be a plastic hose on the end - possibly this is high-demand vacuum source for things like power brake booster - this engine came from a RHD car, correct?
A10 - I think this is engine coolant to heater cores or other destinations.
A11 - Same as A9 - if it connects to the intake, it's probably vacuum source for something.
A12 - Also coolant source for something??

As far as I know, these motors do not have dry sump - but I could be completely wrong.

EDIT - WOW - Poole posted his reply as I was crafting mine. I did pretty good concerning I've never seen the underhood of one of these cars. Completly missed on the CC actuator.

david s poole · #13 12-12-2006, 10:51 AM

wbrian63 at least you found a-8 it was hard to see with red on red but self explanitory engine wiring harness and definately right hand drive[the angle on the brake booster line is a dead giveaway].

Phillblanchard · #14 12-12-2006, 11:03 AM

wow, thanks for the response!

right so, this transmission modulator and vac line A5, what does it do and do i definitely need to keep it conected to a vac source if i want to use the tranmission?

Can i remove the suspension pump and if so does anything require blanking off? or is it best to leave attached? A2

Can i remove and dump the distributor without any problems or does the oil pump run from the same gear? if i just pulled it and dumped it & blanked off the hole would everything still be ok? im aiming to run DIS with the megasquirt.

ive removed the distribution assembly bit and got down to the intake manifold. theres 2 things screwed into the manifold which look like temp switches/sensors but have vac pipes attached (well did by the looks of it) what do these do?

Thanks again

yes its from a RHD model.

david s poole · #15 12-12-2006, 04:27 PM

the only vac line you will need is the one to the modulator.if you remove the suspension pump you will leak a lot of oil.i think you can get a blanking pce from mercedes[off the 560sl engine] you should be able to do away with the dizzy.those vacuum temp switches will not be needed.
